The function transforms a vector of point biserial r values to their normal approximation. It also works for the correlation r.

transformRtoZr(r)

Arguments

• r: A vector of r-values

Returns

value of normal approximation of point biserial r

Examples

reproducer::transformRtoZr(0.4)
# [1] 0.4236489
Zr <- reproducer::transformRtoZr(c(0.4, 0.2))
Zr
# [1] 0.4236489 0.2027326
